MEANS FOR REMOVABLE SECURING 'IHE HEADS OF METALLIC BARRELS.

To all whom it may concern:

Be it known that I, CHARLES T. DRAPER, a citizen of the United States,residing at Cleveland, in the county of Guyahoga and State of Ohio, haveinvented certain new and useful Improvements in Means for Be movablySecuring the Heads of Metallic Barrels, of which the following is aspecification.

all of these members,

My invention relates to improvements in means for removably securing theheads of metallic barrels, and has for its object the construction of abarrel adapting it to be completely opened at one end for the pur-' poseof packing and cleansing the same.

It is highly desirable to provide a construction which will permit theready cleansing of the interiors of metallic barrels and adapt the sameas well for the shipment of solid commodities.

To this end, the mouth of the barrel should be left unobstructed, metalbody thereof preferably is left uncut and integral to avoid the placingof unequal strain upon the same. In providlng a removable head formetallic barrels, it is necessary to insure substantially a hermeticseal under conditions of severe usage during handling and shipmentthereof.

Accordingly. it is my primary purposeto reinforce the joint between theremovable head and body of the barrel, while avoiding any obstructingparts or flanges positioned interiorly of said barrel, which wouldrestrict the opening or interfere with cleaning the barrel in any way.

Briefly described, my improvement consists in providing the cylindricalbarrel body with an" over-lapping metallic head, reinforcing the head byan inner ring, an the adjacent body'by an outer ring, and over I haveapplied a sectional annular channeled member equipped with v suitablescrew-acting or wedging means, whereby the parts'are secured firmlytogether. a

Details of my improvements may be more readily understood by makingreference to' the accompanying drawings, wherein Figure 1 is afragmentary view of the upper portion of a barrel shown broken away andin partial section as equipped-with my improvements. Fig. 2' is anenlarged sectional view through the rim. Fig. 3 is" a fragmentary viewillustrating modified Specification of Letters Patent.

wedging means for securing the channeled THE mmrnn MANUFAC- member. Fig.4 is a plan view showing onehalf section-of the securing'channel upon asmall scale, and Fig. 5 shows enlarged views of counter-sunk screwsinsertible therein.

Throughout the several figures of the drawings, I have employed the samecharacter of reference to indicate similar parts.

The body a of the barrel is formed of cy 'lindrically shaped sheet steelhaving a lower head or bottom (not shown) of any ap-' proved type, andbilges a whereon the bar-' rel 1s adapted to roll.

My improvements relating solely to the removable head-securing means forthe bar-. rel, the featuresthereof alone are shown in detail.

A reinforcing exterior ring I) is provided adjacent to the upper end ofthe cylindrical body a, over which the edge a is rolled. The metallichead 0 has an entering rim 0 with its edge 0 annularly rolled to engage1t lhefiezdge (1., over which it is adapted closely A suitable elasticpacking d is interposed between the curved abutting edges a, c".Interiorly of the rim 0 there is positioned an inner ring 6, which isangular in crosssection and conforms closely to the curvas merely forthe sake of c'learness in illustrat- 'ing the same.

In order to secure these parts in hermetic seallng relation, twosemi-circular or sectional channeled members f are adapted to bepositioned upon the upper flange e of the-inner ring.

Retaining pins f, which'engage :corresponding holes drilled-in saidflange, serve initially to secure the clamping channels upon the head.Along the lower edge of the channels, at frequent intervals, there areprovided a plurality of set-screws g, which I the exterior ring I) frombeneath, and thereby eral members of the removable ,head tightlytogether to effect a hermetic seal between the Although I prefer theset-screws for securing the parts together, I have provided insubstitution therefor, short wedges h, which are adapted to be insertedthrough clamp the sevy g edges a, 0", respectively of the 1 i body andcover.

cut-away portions f" of the channels f, and maybe driven between ring I)and the adjacent lower flange of. said channel. This constructionobviously avoids the use of vprotruding set-screw' heads, but otherwisener face of the channel, and being of great rigidity, the. several partsare capable of withstanding all ordinary-commercial usage to whichmetallic barrels are subjected.

Merely by releasing the set-screws, and removing the two sectionalsecuring channels, the removable head is freed from the barrel body andin consequence, said barrel may be readily opened. No interiorlyprotruding parts are employed for closing or locking the removable headin position, and in consequence, \the barrel may be more easily packedwith solid commodities and may be more readily cleansed, than arestructures containing such disadvantageous features. Although theremovable head and locking means are of great strength and protectivevalue, the contours of the parts are such as to lend themselves tosimple rolling, welding and tapping methods, which insures a relativelylow costof manufacture.

Sheet metal receptacles present, peculiar problems with respect toremovable closures,

for the reason that it is desirable to avoid any mechanism which tendsto place a buckling strain upon the body or head ltself.

- solid annular rings to secure. a vertical pres- My improvedconstruction, places all of the sealing strain upon a spllt clampingmember or members, which reacts against sure between the rims of thehead and barrel body, through an intermediate I gasket While theclamping mechanism is exterior of the head, it is capable .of suchcompact construction; conforming closely to the rings and rims as itdoes, that the chime is increased but llttle in diameter.

adjustment, my improvement is not necves'sarily restricted thereto.
